JOHN EDWARD SGHLIEPER, OF ALLEGHENY, PENNSYLVANIA.

FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 536,660, dated April 2,1895.

Application filed January 30, 1894- Serial No. 498,520- (No model.)

To all whom it may concerns-1 Beit known that I, JOHN EDWARD SoHLIE-PER, a citizen of the United States, residing at Allegheny, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Feed-Water Heaters; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, inwhich- Figure 1 indicates a vertical central section of my improvedheater. Fig. 2 is an enlarged detail of swimmer and blow off valve.

My invention relates to that class of heaters, in which exhaust steamfrom engines, is utilized to heat water to a considerable temperature,previous to its admission to a boiler or boilers, and my object is notonly to heat water, as aforesaid, but to wholly prevent the introductionof oil, dirt or other sediment into the boiler, and to this purposeconsists in the novel construction and arrangement of parts, hereinafterspecifically set forth, reference being bad to the accompanyingdrawings.

I will now describe my invention, reference being had to theaccompanying drawings, forming part hereof, in which like lettersindicate like parts Wherever they occur.

Referring to said drawings A is a heater, adapted to heat water fromwaste or exhaust steam, from an engine not shown. To accomplish thispurpose, steam admitted to the heater through the exhaust pipe B whichis connected with the upper portion a of the same acting on the waterfalling through the perforated pipe 0 raises the temperature of saidwater. The upper portion of said perforated pipe 0 is connected with theinner end of the water supply pipe d and the lower end thereof is boltedor otherwise suitably secured upon the upper end of the bell ewhich issuspended therefrom. The lower edge of the bell is perforated to permitthe heated water overrunning from the perforated pipe to fall into theheater.

b is a pipe opening to the atmosphere and controlled by a valve adaptedto be opened when the steam becomes excessive in the heater.

' 'i is a pipe for the purpose of conveyingexhaust steam from adifierent engine, if desirable, than that connecting the heater by thepipe 13, and to discharge the same beneath the apex of said bell.Secured to and connected with said heater below the water linetherein,is a chamber j which is connected with a pump, not shown, by thepipe is. the opening Z between said chamber and heater is of muchgreater diameter than the pipe connecting said chamber and pump, and ona plane below the same, thereby enabling the same water level to bemaintained in said chamber, as in the heater, and preventing theintroduction of oil or other impurities on the surface of the water inthe heater into the boiler or boilers fed by the pump. Secured in theupper head of said chamber is a vertical pipe m open to the atmosphereand provided with a valve n to which is secured a gage glass m, asshown. Connected with said pipe m and heater above the high water line,is a short horizontal pipe 0 which is provided with a steam alarm 19adapted to operate when the steam pressure becomes excessive in saidheater, upon which the safety valve on pipe?) will operate and reducesuch excessive pressure. Suitably secured in a bracket q secured in theinner-surface of said heater, at the high water level therein, is aperforated pipe 1" elliptical in form, whereby oil, 850., may be drawninto and collected in said pipe, and discharged therefrom through thepipe 8 in the side of said heater, at such times as the valve 15controlled by the swimmer u is opened. Said swimmer is attached to theend of a forked shape arm n which is pivotally attached at the pointsw-w to the bracket o secured to the inside of the shell of the heaterand is adapted to be elevated by the height of the water, as shown bythe dotted lines, thereby drawing the lower end of the link at anddrawing the piston 2 attached to the upper end of the link an inwardlyand opening the port of said valve 25 and discharging the contents ofsaid pipe as heretofore stated. V a is a blow off pipe, secured inbottom of heater, and may be provided with a valve.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a water heater, the combination of a heater adapted to heat waterby exhaust steam, and a chamber adapted to be connected to a pumpconnected and communicating with said heater below the low Water linetherein, by an orifice of greater diameter than that connecting saidchamber and pump, and below the line or plane of the pipe connectingsaid chamber and pump, substantially as and for the purpose set forth.

2. In a feed water heater, the combination of a shell, a water supplypipe entering the top of the same, a perforated pipe and bell suspendedthereon in the upper portion of said shell, and a chamber connected andcommunicating with said heater below the low water line therein, byanorifice of greater diameter than the pipe connecting said chamber withthe pump, and below the level or plane of the same, substantially as andfor the purpose set forth.
